The adhesion of microorganisms and the subsequent formation of mineralized layers in biofilms are of great significance in inhibiting the corrosion of metal materials. In this work, we found that the adhesion and subsequent mineralization of on the surface of low-alloy steel are influenced by the molybdenum in the material. The addition of molybdenum will lead to increased adhesion of on the material surface, and the subsequent biomineralization ability has also been improved. Through transcriptome and physiological and biochemical tests, we found that molybdenum can affect the chemotaxis, mobility and carbonic anhydrase secretion related genes of , and then affect the formation and mineralization of the biofilm of .
微生物的黏附以及随后在生物膜中矿化层的形成对于抑制金属材料的腐蚀具有重要意义。在本研究中，我们发现低合金钢表面上[具体微生物名称未给出]的黏附及随后的矿化受到材料中钼的影响。钼的添加会导致[具体微生物名称未给出]在材料表面的黏附增加，并且随后的生物矿化能力也得到了提高。通过转录组以及生理生化测试，我们发现钼可影响[具体微生物名称未给出]的趋化性、运动性和碳酸酐酶分泌相关基因，进而影响[具体微生物名称未给出]生物膜的形成和矿化。
